Air and clinker leakage preventing grate cooler module

Abstract

The invention provides an air and clinker leakage preventing grate cooler module, which can be combined into a grate cooler. The grate cooler can be formed by connecting multiple air and clinker leakage preventing grate cooler modules longitudinally, and accordingly modular production of the grate cooler is realized and the grate cooler is free of air leakage and clinker leakage. The air and clinker leakage preventing grate cooler module comprises an underframe, trays, driving boards and grate plates. Bottom plates of the trays are provided with vent holes. Movable push rods are connected to the upper portions of the driving boards, and the lower portions of the driving boards are connected with a driving device. Each grate plate comprises a support and U-shaped bending plates, openings of two adjacent bending plates are opposite to each other, side plates of each bending plate with the upward opening are connected with inner bottoms of the bending plates which are provided with the downward openings and located on two sides of the bending plate with the upward opening, gaps are reversed among side plates of each bending plate with the downward opening and the inner bottoms of two bending plates with the upward openings, the side plates of each bending plate with the upward opening are provided with air holes, an air outlet is arranged at the bottom of the support, and gaps are reserved among the bottom of the support and the bottoms of the bending plates with downwards openings. Besides, partition plates are arranged between the trays and the supports, and inverted-U-shaped cover plates are arranged on the driving boards.

Description

technical field [0001] The technology relates to a grate cooler module used to form a grate cooler. Background technique [0002] The third-generation grate cooler used for cooling cement clinker generally includes a static grate plate set on a static beam, a dynamic grate plate set on a movable beam, the static grate plate and the movable grate plate are arranged at intervals, and the static beam and the movable grate plate are arranged at intervals. Cooling air pipes are arranged on the beams, and the cooling air passes through the cooling air pipes to cool the clinker on the static grate plate and the movable grate plate, and the clinker is moved through the movable grate plate through the longitudinal reciprocating movement of the movable beam. Since the movable grate plate and the static grate plate will move relatively, the clinker will inevitably leak from the gap between the movable grate plate and the static grate plate, which will also cause air leakage.

AI Technical Summary

Problems solved by technology

Since the moving grate plate and the static grate plate move relatively, the clinker will inevitably leak from the gap between the movable grate plate and the static grate plate, which will also cause air leakage

[0003] In addition, for the third-generation grate cooler, if it is necessary to change the size of the grate cooler, for example, it needs to be lengthened vertically or widened laterally, it is almost impossible and the adaptability is poor
